662 / 976 page ![]() Memory Map and Register Definition MAC7200 Microcontroller Family Reference Manual, Rev. 2 584 Freescale Semiconductor 30.11.2 Register Descriptions 30.11.2.1 DSPI Module Configuration Register (DSPI_MCR) The DSPI_MCR contains bits which configure various attributes associated with DSPI operation. The HALT and MDIS bits can be changed at any time but will only take effect on the next frame boundary. Only the HALT and MDIS bits in the DSPI_MCR may be changed while the DSPI is in the Running state.

The MSTR bit configures the DSPI for either Master Mode or Slave Mode. 0 DSPI is in Slave Mode 1 DSPI is in Master Mode 30 CONT_SCKE Continuous SCK Enable. The CONT_SCKE bit enables the Serial Communication Clock (SCK) to run continuously. See Section 30.12.6, “Continuous Serial Communications Clock,” for details. 0 Continuous SCK disabled 1 Continuous SCK enabled 29–28 DCONF[1:0] DSPI Configuration. The DCONF field selects the configuration of the DSPI. As only the SPI configuration is implemented on the MAC72xx, the DCONF bits must always be set to 00..
